interlocking'fastener.construction as shown in my application that wasfiled April 28,

'1924, Serial No. 709,643, and the object of my improvement is toprovide stop means for limiting the closing movement of the slide in theform of a unitary piece that` serves by its lateral ends to connect theindividual s ringmembers to the fabric and that has the intermediateportion vof appreciable length so as to provide for a permanent andpositive lateral spacing of the adjacent portions of said springmembers.

In the accompanying drawing Figure 1 is a plan view of a set of fastenerdevices mounted onthe-two sides of a gap in fabric or the like, a slidefor operating the same, a'stop device at the Xedly closed end, anda'bridging stop device embodying my invention at the other end.

Figure 2 is a side elevation ofthe slide and bridging device.

Figure 3 is a plan view of the blank for the bridging devi-ce.

Figure 4 is a sectional View on the line 4 4 of Fig. 1 showing thebridgingdevice and the adjacent portion of the slide in the engagingposition with said bridging device, other parts of the slide being shownin side elevation.

Figure 5 vis a rear elevation of the bridging device.

My improved fastener combination comprises a set of fastener devicesthat consist of a series of left hand active locking inembers on theleft side of a gap l11 between the opposed edges 12 of a pair of strips13 or the like of fabric and a series of right hand active lockingmembers 14 on the right side of said gap 11 and which locking mem? bersare in the case of each series integrally connected and parts of a coils ring struc ture. That is to say, the left and active locking members10 are parts of the left spring 15 and the members 14 are parts of thespring 16.

At the rear ends the springs 15 and 16 are ixedlyninterlocked and heldtogether as well assecured tothe fabric by means of a clip 17 that hassuitable prongs for penetrating lthe fabric and being bent over t0eii'ect the necessary holding, said clip 17 serving as a stop forlimiting the inward movement of the slide 18 1n comprises a top plate 19, a bottom plate 20, with a space 21 between said plates for ad-`mitting the springs 15 and 16 and an inte-J' gral connecting neck 22 ofreturn bend form for interconnecting said lates 19 and 20.

The top plate '19 has pen ent lianges 23 at the lateral edges forguiding the springs 15,

and 16.

4 The slide 18 has'at the lower or rear end a mouth or opening 25between the plates 19 and 2O that is an operative fit for the twosprings 15 and-16 in interlocked position.

At the upper or forward end of the slide 18 the springs 15 and 16 maketheir exit in divergent relation through individual spaced outlets 26.Upper guide walls 27 are provided by swaging the material at thejunctions of the top plate 19 and bottom plate 2O respectively with thestructure of the neck 22, the two armsof the neck being pressedsubstantially together, said guide walls 27 convergin inwardly anddownwardly or rearward y, and meeting in substantially V-formatio 1Adjacent the apex 28' of said V-formation the arms 29 of the neck 22 areperforated to admit a rivet structure 30, substantially as in theapplication above referred to. In

the present 'instance and correspondin to- .nov

substantially the usua1 l manner. Said vslide 1.8 is iliade of sheetmetal and lation thereto, and the rear end thereof is in the form of areturn .bend structure 34 Ithat los 25' `slidenl is withdrawn from@ "ithe fully locked position said nose 37 is lmsed Within a cavity 38 thatis provided /in the part 39 that may be briefly referred to as theVforwardstop.

5 -Said cavity 38 is at or adjacent the middle portion of the forwardstop 39 and the lateral ends 40 are used as the securing The yoke 43 isnarrowerthan the walls 41 and 42 so as tof-:provide clearance for thematerialiof the .strips 13 and to permit the same Vto extend beyond thestructure of the forward 89.
